Definitions

  • the present invention relates to a belt locking device for a vehicle seat, in particular a motor vehicle seat, with the belt locking device having a moveably attached belt lock, a tightening unit supported on a structure-fixed support element, and a transmission means acting between the tightening unit and the belt lock, wherein, in the event of a crash, the tightening unit pulls the belt lock from an initial position into a crash position by means of the transmission means.
  • a belt locking device for a vehicle seat in particular a motor vehicle seat, has a moveably attached belt lock, a tightening unit supported on a structure-fixed support element, and a transmission means acting between the tightening unit and the belt lock, wherein, in the event of a crash, the tightening unit pulls the belt lock from an initial position into a crash position by means of the transmission means, and wherein the position of the tightening unit can be changed in a longitudinal direction of the transmission means relative to the support element.
  • the transmission means is tension and pressure proof and flexible, with the option of a spring or another energy storage means keeping the belt lock in an upright position.
  • the position of the tightening unit can preferably be changed by means of a motor, i.e. the tightening unit is driven by a motor, on the one hand, in order to define a specific movement and, on the other hand, to increase comfort.
  • a motor i.e. the tightening unit is driven by a motor
  • it is preferably located in a structure-fixed casing which also houses the motor and in which the belt lock is supported for example through a deflector and the spring.
  • Fixing the casing to the structure can be realized with e.g. the seat frame, the upper rail, the lower rails or the vehicle structure.
  • the support element is in the form of a motor-driven rotatable spindle nut supported inside the casing, into which is screwed a spindle, the rotation of the motor being translated into a shifting of the tightening unit with simultaneous gear reduction.
  • the spindle can be part of the tightening unit, i.e. of the tightening casing or, optionally, can be an independent element bearing against the tightening casing or being attached to it.
  • the transmission means is preferably led through the spindle, which would then have to be hollow (e.g., define a passageway).
  • the invention is applicable to all vehicle seats having a belt tightener.
  • different situations such as, for example, sitting down, opening the door, turning off the engine, or crash, may cause the comfort position to be assumed.
  • FIG. 1 is a section through the exemplary embodiment in the comfort position
  • FIG. 2 is a lateral view of the exemplary embodiment in the initial position
  • FIG. 3 is a lateral view of the exemplary embodiment in the comfort position
  • FIG. 4 is a lateral view of the exemplary embodiment in the crash position
  • FIG. 5 is a schematic lateral view of a vehicle seat
  • FIG. 6 is a section through the exemplary embodiment in the original position.
  • a belt locking device 1 for a vehicle seat 3 of a motor vehicle is fixed to the structure of the vehicle seat 3 on the side of the seat 3 that is adjacent to the vehicle's center tunnel.
  • the purpose of the belt locking device 1 is to releasably attach a safety belt 5 of the vehicle seat 3 .
  • the arrangement of the vehicle seat 3 within the vehicle and the vehicle's normal direction of travel define the following directional indications.
  • the belt locking device 1 has an oblong casing 11 whose longitudinal direction aligns with the direction of travel, and a pyrotechnical tightening unit 13 that is moveable in the direction of travel, is partly arranged inside the casing 11 , and is otherwise protruding frontward.
  • the belt locking device 1 furthermore has a deflector 15 arranged at the rear end of the casing 11 , a spring 17 in the form of a helical spring pointing obliquely away from the deflector 15 frontward, and a belt lock 19 arranged at the upper end of the spring 17 for receiving the belt tongue of the safety belt 5 .
  • a traction and pressure proof, flexible transmission means 21 in the present case a steel cable, is run from the tightening unit 13 backward and obliquely upward via the deflector and through the spring 17 towards the belt lock 19 , and is attached to the belt lock 19 .
  • the transmission means 21 thus acts between the tightening unit 13 and the belt lock 19 .
  • the transmission means 21 is attached so that it can move in the longitudinal direction of the transmission means 21 relative to the casing 11 , and flexibly transversally to the casing 11 .
  • the spring 17 is enclosed in bellows 23 that extends between the belt lock 19 and the deflector 15 .
  • the bellows 23 provides protection from dirt and other external effects.
  • a motor 25 is supported in the casing 11 .
  • the motor 25 is in gear connection with a spindle nut 29 by means of a spur gear 27 .
  • the spindle nut 29 is screwed onto a non-rotating, hollow spindle 31 forming a rear part of the tightening unit 13 and through which the transmission means 21 is running towards the rear.
  • the spindle nut 29 which is rotatably supported in the casing 11 , acts as a support element for the tightening unit 13 . In the initial position, the rear end of the spindle 31 is located at least approximately within the spindle nut 29 .
  • the belt locking device 1 executes the known belt tightening function, i.e. the tightening unit 13 ignites and a part thereof rushes forward—supported on the part that is connected to the spindle 31 and pulling the belt lock 19 downward by means of the transmission means 21 , against the force of the spring 17 .
  • This crash position is shown in FIG. 4 .
  • the safety belt 5 being locked in the belt lock 19 is tightened, i.e. a possible looseness in the belt is removed, so that the passenger is moved forward as little as possible.
  • the belt locking device 1 also has a comfort function because of a change in the position of the tightening unit 13 .
  • the motor 25 When a passenger sits down on the vehicle seat 3 , this event being registered by the seat occupation recognition sensors, the motor 25 is activated, pushing the spindle 31 backward by means of the spindle nut 29 .
  • the tightening unit 13 that is carried along also moves the transmission means 21 backward, so that the spring 17 can use the freed path to extend the belt lock 19 , as is shown in FIG. 3 .
  • the belt lock 19 thus becomes more easily accessible for the passenger.
  • the motor 25 moves the spindle 31 forward, i.e. it again pulls in the belt lock 19 , until the optimal belt run is achieved and the looseness of the belt has been removed.
